[BUG] OpenCV Not Working on MacOS Big Sur 11.6.4

Describe the bug
Hi guys,

I'm having an issue with opencv lib on my MacOS Big Sur 11.6.4.

I followed the installation instructions and it did not work for me.
I mean, the opencv installation had no errors, but when I tried to run a simple nodejs project with the lib installed, I received the error below.

Does anyone know how to fix this?

The simple nodejs project I used can be found here: https://github.com/danilo-dsf/test-opencv

To Reproduce

$ brew install pkg-config

$ brew install opencv@2

$ brew link --force opencv@2

$ mkdir test-opencv

$ cd test-opencv

$ yarn init -y

$ yarn add opencv

$ touch server.js

$ nano server.js - (Write a simple console log and import. the opencv lib)

$ node server.js

Expected behavior
Expected tho work fine.

Update

I have noticed that opencv@2 has a deprecated warning at homebrew page.
So I've installed the opencv@3 package and it worked fine.

That been said, I've opened a pull request updating the install instructions for macOS in the readme file: #685
